Larry has a simple repair, but maybe complicated originated problem.
The brakes initially grabbing may be related to leaking inner axle
seals, which are, or have already, contaminated the brake shoes,
swelling them..
After the shoes get warm, they expand away from the shoes.
The shoes, themselves, may need cleaning, or replacement.
the brake return SPRINGS might just be stretched and need replacing.
The wheel cylinders should be opened up and checked for ridging and/or
crusty-ring formation.
The Centerplane big-support-guy might be warped, or the five 9/16"
bolts, that hold the shoes (IIRC) to it may be over-tightened (35PSI is
required, IIRC).
None of this stuff is real complicated to do, but, Larry's problem may
be related to one or more causations.

Well Larry, my 58 DeSoto does the same thing. It was a brute when I
had a gravel driveway. Let me know if you figure it out.
After a day or so of use the brakes are fine. I sort of feel they
might be just dragging a little and then sort of bond when left to sit.
When I pull the hub, everything looks ok. I will be converting to
disk fronts and a late 60's rear end eventually just for
reliability.
Amp gauge sounds very much like the regulator to me. Probably just
needs the points burnished. Unless the commutator is coming apart,
I wouldn't think brushes would be the problem at low RPM or
idle.

I had the 57 out for a short run
today. Every time it sits for a time (couple weeks in this case),
it will seize up. By that, I mean I can put the transmission in
gear, floor it and, although I can feel it straining, it does not
move. When it breaks free, it spins the wheels (gravel drive), and
goes a bit, then seizes up again. Works better if I put it in
reverse. Once it gets up the drive a bit, it drives fine. Not
sure if it is the brakes, the e-brake, or what. Does not pull left
or right when braking, and the transmission fluid is fine.
Other problem I noted today is the amp gauge fluctuates constantly back
and forth, not in any rhythm, but constantly. Could it be the
brushes in the generator, the voltage regulator, or the gauge
itself?
Not many more days when I can get the FL cars on the road here, as the
first hard freeze is due tonight. Bah Humbug!
